[CentOS-virt] (KVM) How can I migrate VM in a non shared storage environment?

[Poh Yong Hwang]

Hi All,

Thanks for all your suggestion. Just a check, if i have a full backup on the
server but due to the different specs of the hardware so i am unable to do a
bare metal restore, can i just dump all the folders under /var/lib/libvirt
which also includes the images folder? Will it work that way?

Here is the folders in libvirt:

[root at pop-kvm-web libvirt]# ls
boot  images  iptables  network  qemu

Thanks!
